I'm using Windows 10 Pro 32-bit on a 7-year-old Dell desktop PC. In the past couple of months (ever since my PC was updated to Creators Update, by this may be a coincidence), when I use the UI to shut down my PC, I have to wait about 2 minutes and 30 seconds before it actually starts to shut down.
During that time, I can use the PC normally; there are no processes shown in Task Manager using up any considerable CPU time. After 2m30s, the PC then starts to shut down without any further warning.
This happens irrespective of whether or not I'm connected to the Internet. It only happens when I use the UI (i.e. either: click Start -> Power -> Shut Down, or: WinKey+X -> "Shut down or sign out" -> Shut down). If I give the command
shutdown /s /t 0 in the Command Prompt, it shuts down immediately.
Any ideas how I can find out the reason for this delay?
